I was once told by a friend to be positive and that I'm the hero of my own adventure (I am not lonely at that time by the way, I was moving out of my hometown, which is funny enough since I realised after that people seem to think it's weird if you move out of town for any reasons aside from job or college opportunities). Anyway, I was indeed going on adventure by moving out of town but I never thought of myself as hero before or after. I don't like the expression because it sounds like stoking and inflating the ego. I have a friend who seems to have that mindset when we were younger, but when our 20s came, he fell into depression for not attaining his dreams and desires.

I think a lot of us were raised to hope and to be like a superhero making big changes to the world. Personally, I see myself as more like a traveller or soldier; experiencing and absorbing the world without necessarily trying so hard to shape the world to our own liking, and also facing challenges and adversities gracefully. Live your life to the fullest as you wish, but what I'm trying to say is be humble enough you're only human--not a god-- and know when to fight battles.
